Almost the best, and great price point...
I love this toy - I give it to my toughest chewer stuffed up with kibble and p-butter that I've frozen an hour or two - and it's cool to play with unfilled too, as it's pliable and soft/bouncy while being also very durable. Starmark is my 3rd of 3 name brands I will buy for my dogs, due to my need for durability for tough chewers thus limiting what toys/brands I can even pick from (West Paw is one I'm now just trying, and Outward Hound is my usual go to over the years), and to be honest, between price and availability, I really want to move Starmark to my number 1 go to but....from what I can tell, the other two companies have great policies about releasing what/where their products are made (of), and I cannot seem to find out whether or not Starmark is also i.e. food-grade and/or whether they have a guarrented return policy or not so....a star off for that until/unless I can assure myself and you, reader, that the quality is just as good as the other two companies. To be fair though, and due to not being able to find any info on material qualities, this IS the one and only toy I have used, but they are also often sold at many local stores and so many of the other treat-toys in this brand have caught my eye, as far as types of toys available and ease to find if/when a replacement (or double to ship to my sister's dog!) is needed. I am thinking that, from what I've seen/felt at local stores for this brand, the durability is likely on par so...again, all going back to the material choice and manufacturing info, for me, that prevents this being a full 5 stars.

Keeps even the most destructive dogs entertained
I was hesitant to make this purchase but after I bought the starmark everlasting chew ball (which I also highly recommend), I gave this one a try. I was surprised how heavy it was, definitely only to be thrown outside as it is made out of solid rubber and could easily go through the tv screen if not careful. My dog is extremely destructive and this not only is very durable, it also keeps him entertained for up to 30 minutes at a time. I have not used the star mark treats specifically designed for it, but regular kibble fits into the grooves just fine. Also, if you put small pieces of chick-fil-a waffle fries, dogs go nuts for it. UPDATE: This toy keeps my rambunctious beagle mix entertained better and longer than any other interactive dog toys I have bought. Of all the toys my dog currently owns, (Starmark Bob-A-lot, Trixie Chess board, Starmark Treat-Dispensing chew ball, and several Kongs) this toy is by far his favorite and keeps him occupied while I get work done around the house, distraction-free. Because of it's made of such dense material, I do have one potential concern: since it's approximately the same size/weight as a full beer bottle) this toy might not be the best fetching choice if your dog is quick and tries to catch balls/frisbees in mid-air since it could bust up his/her head and teeth with it's momentum if he caught it wrong. - But if you don't plan on using this toy for fetching, it is a fantastic purchase for your furry pal.

The toy is fine. My dog outsmarted it.
The toy itself is durable and my dog enjoys it. The problem is that I guess my dog is too smart. The first time I gave it to her, it took her about 25 minutes to empty it. I thought I found a winner. The 2nd time-8 minutes. 3rd time-2 minutes. Oh well.

Amazing, durable toy!
This dog toy is tougher than a Kong, and seems like it's a lot more fun! My miniature dachshunds absolutely love this toy, so much so that I had to get more so that they didn't fight over it. They can lick and play with it for hours and never get discouraged no matter how deep the treat is stuck inside. There are three channels in the toy, at varying widths, so the toy is great for all skill levels. One of our dogs didn't know how to play with toys at all when we adopted him, so we started him out on the larger of the 3, filling it with peanut butter and treats that he would be able to access more easily. Now he picks the toy up and carries it around with him and can get treats out of all channels. He's learning so quickly! Another pup of ours is a fairly aggressive chewer, and since he can't get his teeth into the channels, he isn't able to pry at it like with the black Kong - which he was able to tear after a while. I also think that this rubber gets a lot more slippery than a Kong, so it is harder for teeth to really penetrate, without slipping. Love this toy! Thank you Starmark!

The Pickle Means Business
This toy is a godsend. The price is unbeatable in comparison to Petsmart/1-800Petsupplies and even Chewy. This was one of many christmas gifts for our high chewer Aussie and our Border Collie mix, they opened it early like all dogs do. We lovingly nicknamed this toy 'the pickle' and the dogs know if we tell them to go get their pickle, they bring it to us to fill with treats! The pickle is a perfect toy for if you won't be home for awhile, or if your dog needs to be occupied for an hour or two. We fill it with peanut butter and dog food, then freeze and it makes a perfect long lasting toy. My only single complaint to think about is that this toy picks up fur and dirt like mad. It seems the rubber is just a magnet for gross stuff on your floors. Our solution is to ask the dogs to bring us the pickle whenever we run the dishes, and throw it in the dishwasher!
